Whether a moon base is needed or even beneficial is a question I have not heard a convincing answer in favor. And even if moon base is indeed needed and/or beneficial to future space exploration / resource extraction why robots cannot more efficiently build (or assemble) such a moon base is another question I need an answer to.

We are sending humans to (or around) the moon now, but it may just turn out to be a wasted effort, done solely for the opulence (or more cynically bragging rights / nationalist propaganda).

If we want to go to Mars, the Moon is a good place to learn. Simple things like how to do trauma medicine in low g; how to accommodate a variety of human shapes, sizes and fitness levels; how to do in situ manufacturing; all the way to more-speculative science like how to gestate a mammal. These are easier to do on the Moon than Mars. And the data are more meaningful than simulating it in LEO. If we get ISRU going, doing it on the Moon should actually be cheaper.

If we don’t want to colonize space, the Moon is mostly a vanity mission. That said, the forcing function of developing semi-closed ecologies almost certainly has sustainability side effects on the ground.

We are nowhere near the capability to launch robots to the moon that can autonomously build or assemble a moon base for any useful definition of moon base.

My 4 year old is extremely excited to watch the launch tonight because it’s manned. I’d say a few billion is worth it if all it does is inspire a new generation of astronauts, engineers, and scientists.

The moon has about the same make up as the Earth when it comes to distribution of elements in the crust. If it's anywhere near 8% like Earth then it makes sense to mine aluminum and other metals on the moon in order to build megastructures in orbit. Since the moon has no atmosphere you can accelerate things using mechanical mass drivers. Basically rail systems. At 5,300 mph you hit escape velocity and can then move payload somewhere with no rockets. It would keep us from polluting Earth too. This is the precursor to O'Neil cylinder type structures. AI robots will probably be the play but you still want a transportation system that works and frankly building a landing zone would improve overall outcomes regardless.
